Ivan and Mischa were born during a blizzard. Fedor, as the only man in the house while their father was away doing business, had to carry their mother to the doctor on the other side of the mountain so that she could deliver the twins.

During a thunderstorm, a group of adventurers led by an Enchanter named Shiroe arrives at Arb and is invited to stay in Ivan's family's barn by their grandfather. Ivan and Mischa are awestruck by the ninja-like AssassinAkatsuki, asking her to show them some of her techniques. The group later gives the twins and their grandfather some food as a token of their gratitude.
